Not that he’s ever been soft on religion, but this recent column in SciAm makes him sound like one of those shrill, militant, rabid, dangerous Gnu Atheists.

I don’t know which is more dangerous, that religious beliefs force some people to choose between knowledge and myth or that pointing out how religion can purvey ignorance is taboo. To do so risks being branded as intolerant of religion. The kindly Dalai Lama, in a recent New York Times editorial, juxtaposed the statement that “radical atheists issue blanket condemnations of those who hold religious beliefs” with his censure of the extremist intolerance, murderous actions and religious hatred in the Middle East. Aside from the distinction between questioning beliefs and beheading or bombing people, the “radical atheists” in question rarely condemn individuals but rather actions and ideas that deserve to be challenged.

Surprisingly, the strongest reticence to speak out often comes from those who should be most worried about silence. Last May I attended a conference on science and public policy at which a representative of the Vatican’s Pontifical Academy of Sciences gave a keynote address. When I questioned how he reconciled his own reasonable views about science with the sometimes absurd and unjust activities of the Church—from false claims about condoms and AIDS in Africa to pedophilia among the clergy—I was denounced by one speaker after another for my intolerance.

Religious leaders need to be held accountable for their ideas. In my state of Arizona, Sister Margaret McBride, a senior administrator at St. Joseph’s Hospital in Phoenix, recently authorized a legal abortion to save the life of a 27-year-old mother of four who was 11 weeks pregnant and suffering from severe complications of pulmonary hypertension; she made that decision after consultation with the mother’s family, her doctors and the local ethics committee. Yet the bishop of Phoenix, Thomas Olm­sted, immediately excommunicated Sister Mary, saying, “The mother’s life cannot be preferred over the child’s.” Ordinarily, a man who would callously let a woman die and orphan her children would be called a monster; this should not change just because he is a cleric.
